Powder box



Filed Oct. 27, 1934 Hill! INVENTOW ROBERTLEDERF/ND Patented Apr. 30,1935 UNITED STATES PATENT OFFICE Claims.

The invention relates to. powder cases or boxes especially adapted for.enclosing a loader or filler element, containing powderor similarmaterial in loose form, together with a puff or similar 5 elementdesigned to apply the powder material.

In a copending application for Letters Patent of the UnitedStates-Serial No. 700,950, filed Dec. 5, 1933, as well as in a furthercopending application Serial No. 738,267, filed Aug. 3, 1934, bothassigned to applicant, there is disclosed a loader element comprising aseamless, one-piece, elastic rubber receptacle having at its outer endclosure means for the receptacle outlet, the closure means in the latterapplication embodying tabs which clamp the elastic container materialbetween superposed rings adapted to afiording closing means for thereceptacle outlet.

The present invention has for an object the provision of a box or caseof thin, though substantial, material to enclose a loader element of theaforesaid nature and, particularly, to secure such element againstrotational movement within its box, more especially when manipulating anassociated cover element by partial rotation thereof, to allow ofwithdrawing powder from the loader element, as well as to reseal' theloader.

A further object of the invention resides in the provision of a box orcase which may be inexpensively finished to provide a pleasingappearance, for example by constructing the same of plastics or moldedmaterial such as a phenolic condensation product.

A still further object of the invention resides in the provision of abox in which a loader element of the nature of that set forth in theaforesaid application Serial #738,267 may be conveniently housed andaccommodated, "and the frictional resistance to collapse materiallyreduced through minimizing of actual lateral contact with the adjacentinner surface of the case.

Still another object of the invention resides in a construction of thebox which will admit of convenient sealing of its contents againsttampering.

In carrying out the invention, a box is provided of a more or lessflexible material such as to allow of slight deformation to therebysecurely hold to the top of the box a suitable lid or cover member.Around its inner wall, moreover, the box is provided with verticallydisposed ribs or projections, spaced more or less to conform to thepositions of the aforesaid tabs clamping the closure means at the outletof the loader element which the box is designed to receive. These ribsthus provide channels into which the tabs aforesaid fit them selves tosecure the loader element against rotational movement relative to itssurrounding case or box, said tabs being held against the sides of theribs. These latter, in addition to anchoring the loader against unduemovement during use, serve to stiffen the box of which they are an in- 5tegral part, so that the same may be made relatively' thin; and, ifdesired for appearance sake and greater degree of flexibility, the boxmay be fluted or indented longitudinally over its exterior wall oppositethe said ribs. 10

The nature of the invention, however, will best be understood whendescribed in connection with the accompanying drawing, in which:

Fig. 1 is a front elevation of the novel box.

Fig. 2 is a vertical section therethrough with loader element inposition; and with the material constituting the box shown on anexaggerated scale.

Fig. 3 is a horizontal section, taken on the line 3-3, Fig. 2, but withthe box cover and temporary seal removed.

Referring to the drawing, [0 designates an outer casing or box which maybe variously shaped, for example, of cylindrical conformation andprovided with the convex bottom ll to assist in directing powder towarda sieve over the top of a loader element resting thereon and hereinaftermore fully described. The said box is preferably composed of moldedmaterial, as a plastic such as a phenolic condensation product; and itswalls are made relatively thin to be more or less flexible. A lid orcover 12 of the same material is arranged to fit over the outer end ofthe box and may be concaved interiorly to provide a space it above thebox to receive a puff or like element (not shown) and manipulated inwell-known manner for withdrawing powder from the interior of said box.

Furthermore, the box is designed more especially to receive a loaderelement for the powder rather than to receive the powder directly. Thus,

a loader element l5 of the nature of that disclosed in the aforesaidapplications and of a diameter somewhat less than that of the box l0,particularly one provided with a plurality of topsecuring tabs H5 at itsouter end, is to be mounted within said box to rest upon the bottom I Ithereof. As shown, a sieve member I! closes the top of the loaderelement, being held thereto by the tabs as is more fully set forth inthe aforesaid application Serial #738,267; and a cover element I1 isarranged to be removably associated therewith in any suitable manner toclose the loader element when not in use.

Heretofore, it has been found that such loader element would have atendency to be displaced angularly or have a rotational movement withinthe box, particularly when removing the said cover element or replacingthe same. With the loader element provided with the tabs I6, these tabsmay be caused to act as restraining means in conjunction with verticallydisposed ribs l8 which project inwardly from the inner wall of the boxto provide a series of longitudinal channels l9 into which therespective tabs are located when inserting a loader into its box. Thesaid ribs, furthermore, serve as bearing surfaces for the outer surfaceof the loader element, displacing it some what from the inner wall ofthe box and thus minimizing contact resistance to collapse of the saidbe provided in the molding of the box and simultaneously, if desired,with the provision of vertical indentations or flutings 20 in the outerwall of the box and located opposite the said ribs. This will providefor a more or less flexible wall, sufficiently stiffened by the saidribs, to satisfactorily retain the cover 12 to the box, and particularlyto accommodate a clamping ring for a temporary seal.

Thus, in shipping or in storing the box with loader element mountedtherein, it is desirable to provide a temporary seal over the sieve 1'!with cover ll and top of said box. This may be accomplished convenientlyby means of a thin sheet of rupturable material, such as transparentcellulose material, and formed into a cap 2| which is then fitted overthe shouldered rim 22 of said box, and is permanently held thereat as bya rigid metal clamping ring 23 forced over its flange.

To obtain access to the loader element, it will then be necessary, ofcourse, first to break the aforementioned seal, which seal not onlyprotects the contents against atmospheric conditions until they areready for use, but insures against tampering therewith. Cover l2 thenfits over the clamping ring 23 shouldering on said rim, and as both thecap and the box are of more or less flexible material, a satisfactoryfit is secured therebetween.

I claim: s v
